Extracellular fluid
Which of the following is a buffer zone between the outside world and most of the cells
of the body?
-cell membrane
-red blood cells
-intracellular fluid
-extracellular fluid
-All of the answers are correct
quickly restore changed conditions to normal (or set point)
Homeostasis is the ability of the body to:
-prevent the external environment from changing.
-prevent the internal environment from changing.
-quickly restore changed conditions to normal (or set point).
-ignore external stimuli to remain in a state of rest.
-prevent excessive blood loss.
hormones
Which of the following is one of Cannon's "internal secretions"?
-hormones
-nutrients
-water
, -inorganic ions
-None of the answers are correct
effector mechanism, negative feedback, sensor
Homeostasis requires a ____, a ____ and a _____ to function (ABC order)
Physiology
scientific study of the normal function in living systems
systems biology
An approach to studying biology that aims to model the dynamic behavior of whole
biological systems based on a study of the interactions among the system's parts.
teleological
approach that focuses on why a certain process helps an organism survive a particular
situation
mechanistical
approach that focuses on how the process helps the organism survive
teleological
"The blood carries oxygen to tissues because tissues need oxygen" is an example of
(teleological/mechanistical) approach.
mechanistical
"The blood carries oxygen to the tissues by binding the oxygen to hemoglobin
molecules in the red blood cells" is an example of (teleological/mechanistical) approach.
homeostasis
process that maintains the stability of internal conditions from external variables
sensor
